This paper presents the operational capabilities and the characteristics of the nozzle flow of the Seoul National University Hypersonic Shock Tunnel (SHyST), a recently added facility designed to produce high enthalpy flows reaching 4.1 MJ/kg through hypersonic contoured nozzles. Within this investigation, emphasis is placed on the design and utilization of a high spatial resolution pitot rake, serving as an essential instrument for quantifying pressure and Mach number distributions throughout the test section. The experimental results confirm the presence of axis-symmetric behavior and spatial-temporal uniformity of the freestream Mach number at the nozzle outlet and along the test section. Furthermore, the study demonstrates an excellent agreement with the predictions of numerical simulation.
